This is exactly what I’m talking about – Vancouver 2010, or Kiel+Munich 1972 are perfect examples for reusing existing infrastructure and upgrading it.

Even London 2012 was a great example – reusing infrastructure, upgrading it, etc is a good way to do it.

Another good idea: One of the recent UEFA cups was hosted by two countries together (actually, several of them were). Which is another good idea, several less developed countries working together to still get the profit off of the games, but sharing the costs.
